Fine wire coil/special section, high elastic deflection

  • ⚠️ Elastic relaxation
  • ⚠️ Fatigue fracture
  • ⚠️ Stress relaxation
  • ⚠️ Operating temperature

2 Material Selection Rationale

Grade 9 Ti-3Al-2.5V — Medium strength, good formability

Grade 9 (Ti-3Al-2.5V) has ~110GPa modulus (half of steel) but high elastic limit. Standard for Ti springs. Solution+aging for optimal elastic properties.

3 Form Selection Rationale

Wire / Small Bar — for fasteners, springs, medical

Wire is the only raw material form for springs. Direct coiling, high efficiency.

4 Manufacturing Process & Services

Core Processes:

Automatic spring coilingPrecision end grindingSolution + aging heat treatmentSurface shot peening

Toll Processing Services:

Vacuum heat treatmentShot peeningFatigue testingStiffness sorting

Process Pitfalls:

  • ⚠️ Spring design stress should be 40-50% of shear yield strength; do not use steel spring design rules
  • ⚠️ Post-coiling stress relief annealing mandatory; otherwise severe elastic relaxation
